Complementary and alternative medical approaches to treating adult neurogenic communication disorders: a review

PURPOSE: This paper reviews studies investigating the effectiveness of treating adult neurogenic communication disorders with complementary and alternative medicines (CAM). CAM is gradually experiencing recognition as a viable treatment approach for a variety of disorders by practitioners and patients. Some patients are using CAM as an adjunct to traditional rehabilitation. Additionally, speech-language pathologists are increasingly using CAM in treating communication disorders. METHOD: This review provides a description of various CAM techniques including acupuncture, hypnosis, relaxation training, dreamwork, biofeedback and homeopathy/herbal medicine. Investigations exploring the effectiveness of each of these approaches as they have been applied to aphasia, motor speech disorders, and cognitive impairments are discussed. RESULTS AND CONCLUSIONS: Little scientific inquiry into the effectiveness of CAM in the treatment of aphasia, motor speech disorders, and cognitive impairments has occurred. Many of the reviewed studies demonstrate inconsistent results; use limited sample sizes; do not include quantitative measures of cognitive, linguistic or motor speech skills; and are poorly reported. This review suggests that further exploration of this area is required before any strong conclusions regarding effectiveness and efficacy of these techniques can be made.
